Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This is a single blinded three-arm randomised experimental study. All of the three experimental groups will be exposed to 15 Instagram images of women with a thin-average level of adiposity. However, only two of the groups will also be exposed to images focused on an aspect of postpartum health information, either infrequently (5 images) or more frequently (15 images).

This intervention will be delivered online via REDCap. Participants will scan the study QR code to read the study information sheet, and if willing to participate in the study, will be able to immediately begin completing their questionnaire (implied consent). In total, the questionnaire will take approximately 30-minutes to complete. The first part of the questionnaire will ask participants about key demographic information, as well as details about their social networking site use, whether they access health information on these sites, whether they would like to access health information on these sites, what type of health information they would like included on these sites, and their current exercising and dieting habits. The second part of the questionnaire will investigate how women view their bodies, and how exposure to images captured from Instagram impacts this. This will involve answering questions about their views towards their body before and after viewing images captured from Instagram to determine their body satisfaction and body appreciation.

For the second part of the questionnaire, participants will be randomised (at the time of competition) to one of three experimental conditions, whereby they will be exposed to their allocated set of images as follows: Group 1: 15 Instagram images of women with a thin-average level of adiposity, Group 2: 15 Instagram images of women with a thin-average level of adiposity PLUS 5 images focused on an aspect of postpartum health information, and Group 3: 15 Instagram images of women with a thin-average level of adiposity PLUS 15 images focused on an aspect of postpartum health information.

One of the questions will prompt participants to click on a link that will take them to a video of their allocated group's images. Each image will be displayed for 7 seconds. To ensure attention, participants will be asked to indicate approximately how many of the images were of women and how many included health information, i.e. "none", "about one quarter", "about half", "about three quarters" or "all of them".

Outcomes
Primary outcome [1] 329949 0
Change in state body satisfaction - Visual Analogue Scales (VAS) will be used to obtain state measures of body dissatisfaction (weight dissatisfaction, appearance dissatisfaction). Participants will be instructed to drag the marker along a line from 0 (none) to 100 (very much) to the appropriate position to indicate how they feel ‘right now’ for each item. Scores on the weight and appearance dissatisfaction items will be averaged to produce an overall body dissatisfaction score ranging from 0 to 100.
Timepoint [1] 329949 0
This outcome will be measured before and after the participants view their allocated set of images, within their 30-minute REDCap questionnaire
Primary outcome [2] 330490 0
Change in state body appreciation - VAS will also be used to obtain state measures of body appreciation. Participants will be asked their current feelings for three items (“Despite my flaws, I accept my body for what it is,” “My feelings towards my body are positive for the most part” and “My self-worth is independent of my body shape or weight”). These items are adapted as state versions of items contained in the Body Appreciation Scale. Scores on the three items will be averaged to produce an index of state body appreciation ranging from 0 to 100.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Consenting participants will be randomised at the time of completion to one of three experimental conditions, whereby they will be exposed to their allocated set of images as part of the completion of their allocated survey.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Block randomisation will be used for this study. The first 100 participants will be allocated to group 1, the second 100 to group 2 and the final 100 to group 3. Study investigators will regularly check participant numbers in REDCap to ensure that once 100 participants have been allocated to group 1, the next 100 participants are allocated to group 2, and the last 100 are allocated to group 3.

Efficacy
Statistical methods / analysis
For this study, we are aiming to recruit a minimum of 300 participants (100 in each experimental condition). This sample size is based on a previous similar study (Tiggemann et al. 2020), where they recruited 100 participants to each experimental condition.

Planned statistical analyses includes descriptive statistics, ANOVA to compare changes in state body satisfaction and state body appreciation between experimental conditions and t-tests to detect changes in state body satisfaction and state body appreciation before and after exposure to experimental condition.
